WEATHER-STRIP.

SFECIFICATION forming partof Letters Patent iNo. 293,413, dated February 12, 1884. A

Application filed 'December 5, 1883. (No model.)

To a/ZZ whom it may concern:

lation to each other that under the impulse of Be it known that I, GUsrAv BURKHARDT, a the spring H one end of the strip tends to procitizen of the United States, residing at Homer, in the county of Champaign and State of Illinois, have invent-ednew and useful Improvements inWeather-Strips, ofwhich the follow- This invention relates especially to weatherstrips for the sills or thresholds of doors; and it consists in the novel construction and arrangement of parts hereinafter described7 whereby such strips are automatically adjusted in different planes when the doors'are opened or closed.

In the 'accompanying drawings, Figure I is a side viewof a door containing myinvention, showing the positions of the parts when the door is closed. Fig. II is a similar view when the door is opened. Fig. III shows the lower portion of the door on a larger scale than in the previous figures, some of the parts being broken away and the whole being in position corresponding to Fig. II. Fig. IV is a crosssection on the line mw, Fig. III. Fig. V shows the lower part of the door on a scale similar to Fig. III, with the parts in position corre spending to Fig. I. "Fig, VI is a crosssection on the line y y, Fig. V.

Similar letters indicate corresponding parts.

The letter A designates the door, hung in a frame, B, above the sill or threshold C, in the usual manner.

D indicates the weather-strip. This strip is made of sheet metal, tvood, or other similar material, and is provided with studs e, which are iitted into slots f of bracket-s G, for engaging the strip with such brackets, the latter constituting guides for the strip, as hereinafter explained. In applying the strip to use, the brackets G are attached to the door ininclined planes, extending downwardly and laterally toward one side of the door, as shownand a spring, I-I, is arranged to act on thestrip with a tendency to force it in the direction of the arrow shown in Fig. III, thereby bringing the studs e to the upperends of the bracket-slots f, the spring being in this example a spiral, and being hung to suitable parts of the door and strip at the opposite ends. The strip and brackets, moreover, are arranged in suchreject beyond the vertical edge of the door,where it is hung to the door-frame, while the lower edge of the strip is brought in a planeabove the lower edge of the door, as shown in Figs.

III and IV, and hence, when the door is opened,

strip inward against the action of the spring H the studs e traverse the slotted brackets G, and, due to the inclined position of the brackets, bring the lower edge of the strip into a plane below the lower edge of the door,so that it is forcibly held in contact with the door-sill, as shown in Figs. V and VI, thus covering the joint at that place. The length of the stripD should be equalto the width of the door, and, in order to reduce the friction of the projecting end of the strip with the door-frame, it is provided with an anti-friction roller, t, journaled at the end of the strip which is adjacent to the door-frame. The strip D and its concomitants are furnished with a shield, J,con sisting of a strip of sheet metal or other suitable n1aterial,which is attached to the door in the proper mannerto cover the strip,ornearly so, 'when it is in the upper posit-ion shown in Figs. III and IV. The required space is created for the working of the strip D by arranging it, together with the inclined brackets G and the shield J, at an oblique angle to the door, as shown in Figs. IV and VI 5 but, in lieu thereof, a suitable casing may be used to receive the Strip.

Heretofore a weather-strip has been connected with a door and guided by pins working in inclined slots and acted on by a spring, so that when the door is closed one end of the strip abuts against the door-frame and is moved lengthwise, so that by the slots and pins the strip is 'caused to descend and come against the floor. Such, therefore, I do not broadly claim. 'A

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the two brackets G G, secured to the lower edge of a door, and

IOO

provided with inclined slots, the strip D,mov ing vertically upon one side of .the brackets, and provided with laterally-projecting pins on one of its vertical sides,which are arranged, respectively,in the slots of the bracket, and a spring, H, acting on the strip, substantially as described.

2. The combination of the inclined guides G, the strip D at one side thereof, the spring acting on the strip to throw one end beyond the Vertical edge of the door, and the friction roller journaledto one end of the strip,for riding against the door-frame when the door is closed, substantially as described.

3. The combination of the brackets G G, attached to the door in inclined planes,and provided with inclined slots, the strip D,arranged upon one side of the brackets, and provided with lateral pins on one side, arranged, rcspectively, in the inclined slots, and a spring, H, acting on the strip, substantially as described.

4. The combination of the brackets G G, at-A tached to the door and provided with inclined slots, the strip D, arranged at one side of the brackets and having lateral pins on one side, arranged, respectively, in the inclined slots, and a spring, H, secured at one end to the door and at the other end to the strip, substantially as described.

5. A Weather-strip consisting of the brackets G, fatt-ached to a door and provided with inclined slots, the strip D, arranged upon one sideof the brackets, and having lateral pins arranged, respectively, in the slots, an antifriction roller j ournaled at one end of the strip, to ride against the door-frame when the door is closed, a spring, H, acting on the strip, and the inclined shield J, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing Witnesses.
